Filet mignon is a highly prized cut of beef, known for its tenderness and lean nature, sourced from the tenderloin muscle of the cow. It's incredibly tender and lean, with minimal fat or connective tissue. Filet mignon has a mild, delicate beef flavor, making it a popular choice for those who prefer a less intense beef taste. It's best cooked to a medium-rare temperature to maintain its tenderness. The name "filet mignon" translates to "cute or dainty fillet" in French.
